Abstract

The invention relates to a disease-resistant gene of upland cotton and application of the disease-resistant gene in cultivating a disease-resistant transgenic plant. The invention initially discovers an npr1 gene which can improve the disease resistance of the plant, constructs a constitutive expression type plant expression vector containing the gene and converts the plant expression vector into a plant cell. Experiments prove that after the gene is expressed in the plant, the obtained transgenic plant remarkably improves the capacity for resisting pathogenicbacteria.

Description

Technical field:

[0001] The invention relates to an upland cotton disease-resistant gene and its application in breeding disease-resistant transgenic plants. The present invention also relates to a construct comprising the gene, a recombinant expression vector containing the construct, a plant cell transformed by the expression vector, and a transgenic plant produced by the transformed cell showing high resistance to pathogenic bacteria. Background technique

[0002] The use of chemical pesticides to prevent and control plant diseases will cause environmental pollution problems, and pathogenic bacteria will develop drug resistance. Genetic engineering is a new way to improve the disease resistance of plants.

[0003] During the long-term co-evolution process with pathogens, plants have formed intricate defense mechanisms to resist the infection of pathogens. In the incompatibility interaction mode, the plant's disease resistance gene (resistant gene, R gene) recognizes a s...
